Every mod, will be having two files with the extension .txd and .dff, For example if it's like bmydrug.txd and bmydrug.dff. And you want that skin for a particular team, just use the name of TXD and DFF given for each skin.So, if we want that bmydrug to be usa skin then name it tobmydrug.txd -> army.txdbmydrug.dff -> army.dff

Staff Skin:This one is my personal favourite...Aiden Pearce, Watchdogs(Name the TXD and DFF to : wmyclot)

USA:(I use it as England in my game, but i advice you all should but it in USA to make it a match)COD AW US MARINE(Name the TXD and DFF to : army)
